错误信息：
Error updating database. Cause: java.sql.SQLException: The server time zone value ‘�й���ʱ��’ is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the serverTimezone configuration property) to use a more specifc time zone value if you want to utilize time zone support.
解决办法：
在数据库连接信息后增加：
?serverTimezone=UTC
例如：
"jdbc:mysql://localhost:3306/fruitdb?serverTimezone=UTC"
